title: Posttranscriptional Gene Silencing Does Not Play a Significant Role in Potato virus X Coat Protein-Mediated Resistance.
abstract: ABSTRACT The expression of a gene that encodes coat protein (CP) of Potato virus X (PVX) in transgenic tobacco plants confers a high level of CP-mediated rresistance (CP-MR) against PVX infection. To determine if posttranscriptional gene silencing (PTGS) plays a role in resistance, transgenic plants expressing PVX CP were challenged against PVX under conditions in which PTGS was suppressed by low temperatures or using viruses carrying PTGS suppressors. The data demonstrate that PTGS does not play a significant role in PVX CP-MR.
